通过对高黎贡山云南黄连做样地调查,对其地理成分和群落成分进行分析.调查结果表明,共收集到维管植物61科94属130种(含亚种、变种).植物群落区系成分分析表明,该植物区系成分较为复杂,该区作为东亚古老植物区系的一部分,与古热带、泛北极植物区系有密切关系,而与古地中海植物区的联系缺乏.热带和温带区系交错十分明显,明显属于从热带向温带过渡的亚热带性质.群落成分分析表明,植物组成种类十分丰富,类型多样;生活型谱显示,该群落以高位芽植物为主,地面芽植物次之;该种群生活于高黎贡山山地针阔混交林或中山湿性常绿阔叶林中阴凉湿润处,生活力强,以种子繁殖和营养繁殖为主.中等的土壤湿度,微酸性、酸性,富含有机质的土壤,中、弱等的光照,以及亚热带温凉湿润的气候是适宜该种生存的生境.
Characteristics of Coptis teetoides Community in Gaoligong Mountain
According to the community characteristics, survey on Coptis teetoides in Gaoligong Mountain was conducted, totally collecting 130 species( including subspecies and varieties)of vascular belonging to 61 families and 94 genera. The floristic characteristics of its community were analyzed. The results showed that floristic component was very complex, as a part of ancient east Asia flora, the flora of distribution area of Coptis teetoides in Gaoligong Mountain was closely related to Palaeotropis and Holarctis, and was a short of relationship with ancient Mediterranean. The characteristics of interlace of tropical flora and temperate flora is very distinct, and had the feature of transition from tropical flora to temperate flora. The results of community composition analysis showed that the plant composition was very rich, the plant type were diversified. The life-form spectrum analysis implied that phaenerophyte was the dominant plant, next came hemicryptophyte. Coptis teetoides population distributed in mountainous region mixed coniferous broad-leaved forest, mid-montane humid evergreen broad-leaved forest. The viability of this species is strong, seminal reproduction and vegetative reproduction are major way. The habitat of this species characterized by subtropical feature, middle soil humidity, slight acid or acid and enrich organic material soil, middle or slight sunlight, warm cool and moist climate, were suitable for exist of this species.
